Upcoming film Cake has impressed us with its intriguing trailer, as well as their innovative take on marketing. Their illustrated posters really stood out from what we’ve been seeing recently.

Now we see Aamina Sheikh and Sanam Saeed, who are playing sisters in the film, in the middle of a savage argument via Twitter. It started with a late birthday wish and ended with a comment on how one sister needs therapy! Ouch…

While you might have already noticed their Tweets, we noticed something on the streets! This is not your ordinary sibling rivalry, because apparently it’s now #TeamZareen vs #TeamZara that’s taking over town.

Spotted in Karachi: Waiters wearing Team Zara and Team Zareen tshirts!

We wonder if celebrities will be joining in and choosing sides too, as that has become quite the norm for film marketing techniques. We’ll have to wait and see just how bitter this Cake might get!
